10 Things You Should NEVER Put in the Microwave
Microwaves make our lives easier — from reheating leftovers to making a quick snack. But did you know that putting the wrong things in the microwave could cause fires, explosions, or harmful chemical releases?
Whether you're living in a fast-paced household or you're just trying to save time, knowing what not to microwave is just as important as knowing how to use it. Here's a list of 10 things you should never put in a microwave, and what can go wrong if you do.
1. Hard-Boiled Eggs (With Shell)

They can explode — even after taking them out!
Safer Alternative: Peel and cut them before reheating.
2. Metal Utensils & Aluminum Foil

Metal reflects microwave radiation, causing sparks or even fires.
Pro Tip: Always remove cutlery and avoid foil-covered packaging.
3. Styrofoam Takeout Boxes

Styrofoam melts under heat and may release toxic chemicals into your food.
Safer Alternative: Transfer food to a microwave-safe container first.
4. Plastic Containers (Unless Microwave-Safe)

Regular plastics can melt, warp, or leach BPA into your food.
Look for: Containers labeled “Microwave Safe.”
5. Hot Chili Peppers

Capsaicin (the spicy compound) vaporizes and can cause eye and throat irritation.
Result: Your microwave — and kitchen — could turn into a pepper gas chamber!
6. Grapes
They can generate plasma (yes, actual fireballs) and may damage your microwave.
Safer Tip: Eat grapes fresh or refrigerate them.
7. Canned Foods
Sealed cans trap steam and can explode when microwaved.
What to Do: Always remove food from the can and place it in a bowl first.
8. Paper Bags

They’re highly flammable and can catch fire easily.
Note: Only microwave popcorn in microwave-approved bags.
9. Nothing at All

Running an empty microwave can cause the energy to bounce around, damaging the interior parts.
Tip: Always put something inside when turning it on.
10. Baby Bottles (Non-Microwave Safe)
Uneven heating may cause hot spots that could burn your baby’s mouth.
Better Method: Use warm water or a bottle warmer instead.
Your microwave is a powerful and helpful kitchen tool — but only if used correctly. Avoiding these 10 items can save you from melted messes, health hazards, and even kitchen fires.
Always check for microwave-safe labels, use proper containers, and when in doubt, play it safe.
